These tables include only the commonest host crystals; lots of Some others exist, which are considerably less usually made use of.
These ions permit the crystal to amplify mild in the laser wavelength by using stimulated emission, when Electricity is equipped to the crystal via absorption of pump gentle (�?optical pumping
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical resources) �?which happen to be utilised as get media for stable-point out lasers. Generally, They can be doped with either trivalent scarce earth ions or transition metallic ions.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
Which geometry, dopant and doping concentration with the get medium are most advantageous rely on many things. The offered pump supply (type of laser diode or lamp) as well as the envisaged pumping arrangement are very important elements, but the material by itself also has some affect. As an example, titanium–sapphire lasers should be pumped with large intensities, for which the shape of a transversely cooled rod, operated with comparatively small pump and laser beam diameter, is much more correct than e.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
Of course, it is very attractive that a offered crystal top Laser Crystal quality is developed persistently, although distinctive laser designs might have a special sensitivity to product parameters.
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Laser modeling and simulation can be employed to reliably decide the ideal crystal Proportions, doping density And perhaps values of additional parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-a few-amount laser acquire media and even a few-stage gain media, one frequently really should Restrict the duration to a value and that is way too short for productive pump absorption, as reabsorption effects would or else spoil the functionality. For facet pumping, additional issues occur into Participate in; In addition to productive pump absorption, it is necessary to get an appropriate spatial shape of the obtain profile.

The medium ought to have a superior transparency (minimal absorption and scattering) in the wavelength areas of pump and laser radiation, and fantastic optical homogeneity. To some extent, this depends upon the standard of the fabric, determined by facts from the fabrication course of action.
With That idea, a single doesn't will need an additional saturable absorber crystal, so that one particular might make far more compact Q-switched laser setups with lessen inner parasitic losses. Nonetheless, undesirable side effects may also occur, such as getting undesirable valence states in the associated ions or Electricity transfers.
